In the case of facultative systems, complete mixing is assumed for the liquid portion of the reactor. The solids that fall to the bottom are not resuspended; hence the balance considers only the soluble BOD. This soluble food is assumed to be distributed uniformly, and if the rate is assumed to be first order, then
| (4-70) |  |
| where S and S o = | the soluble food entering and leaving the system, respectively |
| k = | the first order rate constant |
| ? = | the hydraulic residence time |
If n reactors are arranged in series then,
| (4-71) |  |
where S n is the concentration of the soluble food leaving reactor n.
